Bitcoin purchases are eligible for renewal, but not automatically. A renewal notice would be sent to you by Bitpay prompting you to renew your subscription for another term if desired.

iOS In-App purchased accounts can be extended by using the "Renew" button in the PIA iOS app. The Renew button will extend these accounts for another term identical to the one used to make the initial purchase. (Note: this feature will not renew accounts purchased outside of iTunes)

Some users in specific regions may also be offered additional PaymentWall compatible payment options (mint, ecoPayz, Neosurf, Ticket Surf, etc.); these would also be non-recurring account purchases.
